An experiment was conducted to optimize consumption of Zinc and evaluate of Zinc effects on quantitative and qualitative traits of winter wheat under saline soil condition. It was done by three replications in randomized complete block design. The experiment had four treatments as Control without Zn, 40 Kg.ha-1 Zn as ZnSO4, 80 Kg.ha-1 Zn as ZnSO4 in soil and 120 Kg.ha-1 Zn as ZnSO4 in soil. Ele...

AIM A study was undertaken to investigate the effect of organic zinc (zinc nicotinate, Zn-nic) supplementation (6, 9, and 12 ppm) compared to inorganic zinc (12 ppm) on growth performance, hematology, serum biochemical constituents oxidative stress, and immunity in weaned female Sprague-Dawley rats. MATERIAL AND METHODS A 48 weaned rats (285.20±1.95 g) were randomly distributed to 4 dietary t...

To investigate the correlations among seminal plasma Magnesium (Mg), Phosphorus (P), Potassium (K), Calcium (Ca), Chromium (Cr), Manganese (Mn), Iron (Fe), Copper (Cu), Zinc (Zn), Selenium (Se), Molybdenum (Mo) and Iodine (I) concentrations and semen parameters [1– 15]. 500 fertile and 1000 infertile males provided a standardized semen specimen. Total Magnesium (Mg), Phosphorus (P), Potassium (...

Bacteria respond dynamically to the changes in zinc availability. Repression by the Bacillus subtilis transcription factor Zur requires Zn(II), which binds with negative cooperativity to two regulatory sites per dimer to form, sequentially, Zur2:Zn3 and Zur2:Zn4 forms of the repressor. Here we show that, as cells transition from zinc sufficiency to deficiency, operons regulated by Zur are derep...

Zinc (Zn) is the second most abundant transition metal in the human body. It is an essential cofactor for many enzymes and transcription factors. In addition, it has roles in neuronal synaptic transmission because high concentrations of Zn are accumulated in many synaptic vesicles within the central nervous system in response to presynaptic activation. Zn influx from the extracellular space is ...

this research aimed to study on effect of foliar spraying with zinc (as zinc sulphate), nitrogen (as urea) and iron (as sulphate and chelated fe) on growth parameters, quality of fruit, flower characteristics, chemical constituents and nutrients content of leaves on grapevine. applied nutrients were zinc sulphate (zn) of 0.0 and 1.5gl-1 and urea (n) at 0.0 and 5 gl-1 and fe (1) control (low fe)...

Our current understanding of the intracellular thermodynamics and kinetics of Zn(ii) ions is largely based on the application of fluorescent sensor molecules, used to study and visualize the concentration, distribution and transport of Zn(ii) ions in real time. Such agents are designed for high selectivity for zinc in respect to other biological metal ions. However, the issue of their sensitivi...

While nitric oxide (NO)-mediated biological interactions have been intensively studied, the underlying mechanisms of nitrosative stress with resulting pathology remain unclear. Previous studies have demonstrated that NO exposure increases free zinc ions (Zn(2+)) within cells. However, the resulting effects on endothelial cell survival have not been adequately resolved. Thus the purpose of this ...

Zinc, an essential trace element, is the second most abundant metal in the human body that plays a vital role in numerous biological processes, such as peptide synthesis, DNA synthesis, RNA transcription, metabolism of cells, metalloenzyme regulation, and neurophysiology, and it also induces the formation of b-amyloid, which is related to neurological function. More than 100 enzymes, such as pe...
